The heartwood of a tree doesn't actually do anything. It is center of a tree. It i s non-functioning, darker wood and sometimes dead. Heartwood supplies the flexibility to allow the tree to sway in the wind.

This one requires a bit of explanation. A hardwood tree has broad leaves--oaks, maples, birches. A softwood tree has needle leaves--pines and firs. Since no tree has both kinds of leaves, no tree can produce both hardwood and softwood. Now...every tree contains heartwood and sapwood. The sapwood is to the outside and carries the sap from the roots to the leaves. Heartwood is inside the sapwood, and it's more dense because it gives the tree its strength. So, heartwood is harder than sapwood, but it's relative; maple sapwood is very hard compared to poplar heartwood.
The heartwood is ,as the name suggests, the oldest wood in the tree, it no longer transports sap or nutrients but is vital in the stability of the tree as it keeps it upright and pliable.
The oldest wood in a tree stem is typically located at the tree's core in the center of the trunk, known as the heartwood. As the tree grows, newer layers of wood are added around the heartwood. The heartwood is no longer active in water transport but provides structural support to the tree.
Heartwood is the most inner part of a tree. It is the most inner part because it keeps the tree alive. It is surrounded by 4 more layers of the trunk- the outer bark, inner bark, cambium, and sapwood.
One can buy heartwood from a wood shop or woodcutter's yard. Heartwood is the dense inner part of a tree trunk and it is this section that is mostly used for the hardest timber.

Not all trees have heartwood. Heartwood is the dense inner part of a tree trunk, formed as the tree matures and the inner wood cells die, providing structural support. Some species, particularly certain softwoods like pines, may not develop significant heartwood, while hardwoods typically do. Additionally, the presence and amount of heartwood can vary greatly among different species and individual trees.
The older and darker part of a tree is known as the heartwood. Heartwood is the central, non-living core of the tree that provides structural support and strength. It is typically denser and more resistant to decay than the surrounding sapwood, which is responsible for the transport of water and nutrients. Over time, as a tree grows, the inner layers transition from sapwood to heartwood, contributing to the tree's longevity and stability.
